以双酰肼环合法合成了含1,3,4-噁二唑结构单元的溴代芳卤,然后通过Sonogashira钯催化偶联作用与不同单取代炔反应合成了3个新的2,5-二取代-1,3,4-噁二唑类小分子衍生物,其结构经DSC,^1H NMR,IR和元素分析表征。
An 1,3,4-oxadiazole-based aryl bromide was synthesized from the cyclization of 1,2-diaroylhydrazine in presence of phosphours oxychloride. Then it reacted with different monosubstituted aryl acetylene by Sonogashira cross-coupling reaction to get three new oxadiazole-based compounds. Their structures were characterized by DSC, ^1H NMR, IR and elemental analysis.
